| titleOfInvention | A kind of detection method and application of polymer surface agent content in injection and production fluid of oil-water well |
| abstract | The invention provides a method and application for detecting the content of a polymer surface agent in an injection and production fluid of an oil-water well. The detection method comprises the following steps: (1) preparing a standard solution and a test solution; (2) measuring by high performance liquid chromatography: measuring the above standard solution and the test solution by a high performance liquid chromatograph; wherein the The measurement conditions of the high performance liquid chromatograph are: chromatographic column: chromatographic column suitable for polysurface agent; mobile phase: water and acetonitrile; flow rate: 1.0 mL/min; detection wavelength: 200-205 nm; injection volume: 20 μL; detection device: ultraviolet detector; column temperature: 25° C.; (3) According to the result measured by the high performance liquid chromatograph, the content of the surface polymer is obtained. The detection method has the advantages of fast analysis speed, simple operation, safety and reliability; and the content of the polymerized surface agent in the sample is quantified by the external standard method, with few interference factors, high accuracy, good repeatability and high sensitivity. |
